项目摘要

The chemistry of complexes featuring all-carbon (Cx) or carbon-rich (CxHy, x>y) ligands is a source of immense contemporary interest in the organometallic community. To date the great majority of these studies have been concerned with linear polycarbon ligands and the linear polyenediyl ligands (CH)n. While many of these studies are directed towards establishing viable synthetic routes to these unusual metal stablised organic fragments, and in determining their molecular and electronic structures, there are also many enthusiastic discussions of the potential applications of such materials.More recently hyperbranched and dendritic organometallic complexes with metal centres linked by branched conjugated ligands have begun to attract attention as a consequence of their optical, magnetic and catalytic properties. The vast majority of these systems feature branched ligands derived from 1,3,5-trisubsituted benzene cores, and metal acetylide, vinylidene or vinyl based linkages.Given this interest in both carbon-rich organometallic complexes and organometallic hyper-branched systems it is rather surprising that organometallic complexes featuring branched all-carbon or carbon-rich ligands are less common.We propose to combine Professor Hill's experience in alkyne hydrometallation with Dr Low's knowledge of cross-conjugated alkynes and carbon-rich ligand chemistry to develop a new synthetic pathway to organometallic complexes featuring branched carbon-rich ligands.In order to develop this programme we propose to utilise the EPSRC's provision for Overseas Travel Grants to permit Dr Low to visit Professor Hill's laboratory at the Australian National University's Research School of Chemistry (RSC). Whilst at the RSC, PJL will gain first hand experience in the hydroruthenation chemistry used by Hill in many of his elegant investigations. It is anticipated that at the conclusion of this relatively short (3 month) visit that the new Low-Hill colloboration, based upon the exploration of this novel area of chemistry, will be well established.

具有全碳（Cx）或富碳（CxHy，x>y）配体的配合物的化学是有机金属社区中巨大的当代兴趣的来源。迄今为止，这些研究的绝大多数涉及线性多碳配体和线性多烯二基配体（CH）n。虽然这些研究中的许多都是针对这些不寻常的金属稳定的有机片段建立可行的合成路线，并确定其分子和电子结构，但也有许多关于此类材料的潜在应用的热烈讨论。最近，具有由支化共轭配体连接的金属中心的超支化和树枝状有机金属配合物由于其光学性质，磁性和催化性能。这些体系的绝大多数特征在于衍生自1，3，5-三取代苯核和金属乙炔化物的支链配体，考虑到对富碳有机金属络合物和有机金属超支化体系的这种兴趣，相当令人惊讶的是，以支化的全碳或碳-亚乙烯基为特征的有机金属络合物，我们建议联合收割机Hill教授在炔氢金属化方面的经验与Low博士在交叉共轭炔和碳-丰富的配体化学，开发一种新的合成途径，以有机金属配合物具有支链碳，为了发展这项计划，我们建议利用EPSRC的海外旅行赠款，让刘博士能够访问教授。希尔在澳大利亚国立大学化学研究学院（RSC）的实验室。而在RSC，PJL将获得第一手的经验，在氢化钌化学所使用的希尔在他的许多优雅的调查。预计在这次相对较短（3个月）的访问结束时，基于对这一新的化学领域的探索，新的低山合作将得到很好的建立。
